As part of the work on #51857 and #22316, it would be ideal to have unit tests for the new functionality, but there are currently no tests for the Upgrade/Install component.

Let's add some basic tests, starting with the WP_Upgrader class, maybe Plugin_Upgrader and Theme_Upgrader too.

There are some existing tests for WP_Filesystem methods, as well as for the REST API plugins controller, which may or may not be helpful as a starting point.

This PR adds unit tests for the WP_Upgrader class.

This is a work-in-progress that would benefit from feedback on whether/how to test certain functionality in the WP_Upgrader class.

To check coverage:

# Checkout the PR.
gh pr checkout

# Navigate to your wordpress-develop root directory.
cd /var/www/html/wordpress-develop

# Create the coverage directory.
mkdir -p artifacts/coverage/53997

# Run the tests with coverage enabled.
XDEBUG_MODE=coverage vendor/bin/phpunit --filter Tests_Admin_IncludesWpUpgrader --coverage-html artifacts/coverage/53997

Then navigate to http://localhost/wordpress-develop/artifacts/coverage/53997/wp-admin/includes/class-wp-upgrader.php.html. Note: The URL before /artifacts may be different on your system.

PR 1751 on #54245 uses getMockBuilder().

PR 2463 above uses WP_Upgrader directly and aims to achieve 100% (or as near as possible) line/branch coverage for WP_Upgrader.

#54245 notes that there is accidental coverage of WP_Upgrader elsewhere in the test suite, though a single test class that covers each line/branch and in doing so, demonstrates how to hit each line/branch for future path coverage improvements, would be ideal IMO.

It would be good to get some input on the preferred approach for Core.

Curious how many times it's necessary to creates a ReflectionMethod or ReflectionProperty before something like this is a good idea?

Yep, the make_prop_accessible() helper method exists in various test classes. I've used it before myself, but haven't refactored this class yet.
